MSP430-GCC 8_2_0_0
Build date: 07012019
Release Information
Click on the links in the table below to download.TI has partnered with Mitto Systems Limited to bring you a new and fully supported open source compiler. This free MSP430 GCC compiler has no code size limit.
This compiler can be used as a standalone or can be integrated in Code Composer Studio.
For this specific compiler release, there will be no standalone installer.
Later this year we are going to provide a bugfix release for the 8.2.0.52 compiler release which will also include a standalone installer.
Component versions
- GCC 8.2.0.52
- GDB 8.1
- binutils 2.26.0
- Newlib 2.4.0
- MSP430 header and support files 1.207
Changes in This Release
- Updates to GCC
- Updated to GCC 8.2.
- For the full list of improvements to optimizations, compiler messages, new options and more, visit https://gcc.gnu.org/gcc-8/changes.html.
- Reduced the code size of library functions used by GCC for performing bitwise shifts.
- Added -mtiny-printf option, which reduces code size when using printf().
- -mtiny-printf instructs GCC to use size-optimized versions of printf() and puts(), at the cost of reduced functionality.
See the MSP430-GCC User Guide for more details. - Reduced code size when using the large memory model (-mlarge).
- When -mdata-region=lower is passed to GCC, the compiler will assume that global data objects are in the lower 64KB of memory.
This means MSP430 format instructions can be used instead of MSP430X instructions, when handling memory operands. - The ".lower" prefix is no longer automatically added to section names when compiling with -m{code,data}-region=lower.
The -muse-lower-region-prefix option must be used in conjunction with -m{code,data}-region=lower for the ".lower" prefix to be added. - -mdata-region=lower is now set by default. -mdata-region=none is equivalent to the previous default behavior,
where MSP430X instructions are always used when handling memory operands. - The linker will exit with an error if an object file compiled with -mdata-region=lower is linked with an object file compiled with a different -mdata-region value.
- MSP430X instructions will always be used when handling data which has been marked with the "persistent", "noinit", "upper" or "either" attributes.
- Reduced code size of C runtime (CRT) library code
- GCC now registers global C++ constructors and destructors in the .init_array and .fini_array sections instead of .ctors and .dtors.
The library code to run through the .init_array and .fini_array sections will only be linked in these sections exist and have contents. - Support for transactional memory has been removed.
- GCC now uses atexit() to register C++ destructors, instead of __cxa_atexit().
- Added warning that the "critical" attribute has no effect when used with the "interrupt" attribute.
- Fixed quadratic compile time behavior when attempting to optimize the addition of many __int20 variables.
- Fixed compiler error when using R0 as a register variable.
- Improved warnings when misusing data attributes.
- Disabled C++ exception handling by default.
- -fno-exceptions will always be assumed when building C++ programs, unless -fexceptions is passed to the compiler.
- An alternate version of the C++ libraries, built with -fno-exceptions, has been added to the toolchain.
This version is automatically selected when C++ exceptions are disabled, and significantly reduces code size compared to when C++ exceptions are enabled. - Updates to Binutils
- Improved detection of instructions that will enable or disable interrupts,and added more informative warnings about inserting NOPs before/after interrupt state changes.
- Added -mu and -mU assembler options for controlling whether warnings about interrupt state changes, where the effect on interrupt state is unknown, are emitted.
- Removed unnecessary warnings about NOPs being required before/after interrupt state changes for the MSP430 ISA.
- Fixed sections with ".lower" or ".upper" prefixed names sometimes not being placed exactly where the matching linker script rule specified.
- Removed deprecated assembler option -md.
- Updates to Newlib (C Library)
- Reduced code size when using single-precision float arithmetic library functions.
- Removed support for matherr() from libm.
- Removed support for the SVID and X/Open libm configurations. The default libm configuration is now "IEEE".
- Fixed missing definition of unlink() from the simulator CRT libraries.
Known limitations
- The GDB Agent is not able to connect to MSP430L092 target devices.
- The GDB Agent is not able to connect to RF430FRL15xH target devices.
